Effect of mushroom (Agaricus bisporus) waste in place of deoiled rice bran on production performance, egg quality and nutrient utilization in Rhode Island Red laying hens

Abstract

A feeding experiment was planned to investigate the effect of mushroom (Agaricus bisporus) waste in place of deoiled rice bran on production performance, egg quality and nutrient utilization in Rhode Island Red laying hens. 12 weeks duration feeding trial was conducted on seventy-two, 28 week old laying chickens i.e., 18 birds per treatment having three replicates of 6 birds each. Hens of T1 (control) group were fed with basal diet containing deoiled rice bran as one of the feed ingredients, whereas in treatment groups T2, T3 and T4, deoiled rice bran was replaced with mushroom waste at 1.5%, 4%and 5%, respectively. The laying hens' performance was assessed by recording weekly average feed intake, daily egg production, feed conversion ratio and feed cost of egg production. Results showed that the overall average egg production was found significantly (p≤0.05) higher in treatment groups T3 and T4 than control group. The egg quality parameters in terms of yolk cholesterol and triglycerides were significantly (p
